ADMP401 MEMS Microphone Breakout Module

Description:
The MEMS (MicroElectrical-Mechanical System) microphone is also called a microphone chip or silicon microphone.
This tiny breakout board includes the ADMP401 MEMS microphone. One of the main advantages of this breakout and microphone is the bottom ported input. This means the microphone's input can fit flush against the enclosure of your project. You will not have to deal with trying to solder the microphone's wacky footprint. 
The amplifier on the breakout has a gain of 67 and more than meets the bandwidth requirements of the mic.
The amplifier's AUD output will float at one-half Vcc when no sound is being picked up. The amplifier produces a peak-to-peak output of about 200mV when the microphone is held at arm's length and is being talked into at normal conversational volume levels. So the AUD output can easily be connected to the ADC of a micro.
A pressure-sensitive diaphragm is etched directly into a silicon wafer by MEMS processing techniques and is usually accompanied by an integrated preamplifier. Most MEMS microphones are variants of the condenser microphone design. Digital MEMS microphones have built-in analog-to-digital converter (ADC) circuits on the same CMOS chip making the chip a digital microphone and so more readily integrated with modern digital products.
